AMMs connect users who want to trade cryptocurrencies. If you want to swap ETH for USDC or vice versa, an AMM is where you can make that happen. AMMs provide liquidity using smart contracts instead of waiting for a buyer or seller to appear, which is how it happen in TradFi.

A Decentralized Exchange (DEX) lets you trade crypto assets directly with another person, with no central authority involved. It’s like a farmer’s market for trading, where you get security, transparency, and control over your transactions — minus the annoying crowds.
